PERFORATOR FOR PRINTING-PRESSES.

iSPECIPICATION forming part of Letters Patent No. 380,578, dated April3, 1888.

Application filed June 6, 1881'. Serial No. 240,412. (No model.)

To aZZ 1072,0722. it may concern.-

Be it known that we, ROBERT KENNEDY and GEORGE KENNEDY, both of NewWestminster, in the Province of British Columbia and Dominion of Canada,have invented a new and Improved Perforator for Printing-Presses, ofwhich the following is a specification,reference being had to theannexed drawings, forming a part thereof, in which Figure 1 is a sidesectional elevation of a part of a printing-press to whichourimprovement has been applied. Fig. 2 is an enlarged transversesection taken on line a: a: in Fig. 1. Fig. 3 is an enlarged transversesection taken on line 3 y in Fig. 1. Fig. 4. is a plan view of one endof the perforator, and Fig. 5 is a yielding contact for operating theperforator.

Similar letters of reference indicate corresponding parts in all theviews.

The object of our invention is to provide an efficient device forattachment to printingpresses for perforating blank checks, receipts,&c., simultaneously with the printing thereof.

Our invention consists in an oscillating bar carrying a series ofperforating-teeth and adapted to be supported in the form of theprinting-press; also, in the combination therewith of devices foroscillating the perforatingbar, all as hereinafter more fully described.

The body of the perforator isformed of a bar, A, of metal, having in theupper surface thereof a semicircular groove, a, to which is fitted acylindrical bar, B. To one end of the bar A is secured a block, (3,provided with a dowel, c, entering a hole in the end of the bar A.

The bar B is journaled at one end in a lip, (Z, projecting outwardlyfrom the block 0, and the opposite end of the bar 13 is journaled in 40a lip, 6, formed on the end of the bar A. The block (J is provided witha chamber, f. To the journal of the rocking bar B, inside of thechamberf, is secured a pinion, g, and in the said chamber is pivoted anintermediate pin- 5 ion, 71, engaging the pinion g. In the side of thechamberf there is a guide, 13, to which is fitted a rod, 9', carrying aplate, 7c, to which is secured a'rack-bar, Z, arranged to engage theintermediate pinion, h.

To the upper cud of the rack-bar Z is secured a finger, m,which projectsthrough an opening in the side of the chamberf and extends over thechase D, in which the form is locked. Between the plate k and the wallof the chamber f is placed a spiral spring, j, which surrounds 5 5 theguide i and tends to push the plate It and rack-bar Z outward. Thefinger m is protected by a; guard-plate, n, projecting from the block 0,and extending over the finger and over the chase.

The bar B is provided with a series of perforating-teeth, o. Theperforating device is operated by a contact-piece, E, (shown in detailin Fig. 5,) which consists of a right-angled plate, F, provided withclips 1), for receiving the ends of a bowed spring, G, which is providedat the center thereof with a block, q. The contact-piece is held inplace upon the platen of the printing-press by inserting theright-angled plate F between the clamp 2' and the platen s, in positionto allow the block q to project through an aperture, 15', in the guard nand touch the finger in before the form comes into contact with thepaper carried by the platen. The pressure of the block q upon the 7 5finger pushes in the rack l, imparting rotary motion to the pinion h,which is transferred to the pinion g and turns the bar B throughonequarter of a revolution, bringing the perforatingteeth 0 into theposition of use. The elas- 2o ticity of the spring G permits of acertain movement of the platen or the bed of the press after theperforator is brought into position for use, so that theperforating-teeth are in a. fixed position when they come into contact 85 with the paper. This construction also permits of the withdrawal ofthe perforator from the paper before the perforator is returned to itsoriginal position.

\Vhen the finger m is relieved from the pressure of the block q, thespringj, surrounding the guide 2, pushes the rack Zforward, and thusreturns the perforator to the point of starting, with the teeth 0resting upon the surface of the bar A, so that the roller as it passesover the 5 type is not injured by the teeth of the perforator and theinking of the perforating-teeth is avoided.

The perforator is applied to a printing-press by looking it up in theform with the type.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- 1. In a perforator for printing presses, anoscillating bar provided with a series of perforating-teeth, and meansfor rocking the bar to bring the teeth into the position of use,substantially as described.

2. In a perforator for printing-presses, the combination of the bar A,provided with the longitudinal semicircular groove a, the bar B, pivotedon the bar A and provided with a series of perforating-teeth, 0, thepinion y, secured to one of the bearings of the bar B, the intermediatepinion, h, the spring actuated rack l,provided with the finger m, andmeans, substantially as shown and described, for pushing in the saidrack.

3. In a perforator for printing-presses, the

combination of the bar A, provided with the longitudinal semicirculargroove a, the bar B, pivoted on the bar A and provided with a se ries ofperforatingteeth, o, the pinion y, secured to one of the bearings of thebar 13, the intermediate pinion, h, the spring actuated rack Z, providedwith the finger m, and the yielding contact formed of the plate F andbowed spring G, provided with the block q, substantially as described.

4. The combination,with the finger m, rack Z, spring j, pinions g h, andmechanism connected therewith, of the apertured guard-plate n,substantially as described.
